Beast actually doesn't look too bad on that pic (and this is coming from someone who detested his FC look!).

But they need to do something about Mystique's hair. I've always thought this, even with Rebecca's Mystique (though Rebecca's Mystique always had the good fortune of being in dimly-lit scenes).

She looks like she has mascot hair. Back in 2000's X-men days, before we ever saw pics of Mystique, her hair was described as slicked-back. I think they need to give it that "wet slicked-back"-look. Or at the very least, play around with the lighting!
